NUA timing/order ?

  I have a 401k I have taken nothing out of or touched.  

I would like to convert some of my 401k to an Ira this year. Later this same year, I may exercise an NUA, and pull out the rest of the 401 k.   So the 401k would be empty by the end of the year 

 

i’m being told I cannot do it in that order. They tell me  I would have to exercise the NuA FIRST and empty the 401k by year’s end.     That doesn’t sound right to me.

Can anyone point to the IRS document which states what the requirement is?  This financial person, or I, am mistaken.
